La posición que ocupan los ancianos en sus comunidades depende de múltiples factores, entre ellos el tipo de organización social, económica y política, así como el sexo de los individuos. Por ello, dicha posición ha oscilado entre la gerontocracia y la marginación de los mayores. En este caso se pretende conocer cuál fue la posición de las ancianas en la sociedad maya prehispánica de Tierras Bajas a través de la Iconografía. Los objetivos de esta investigación eran seis, desarrollados cada uno de ellos en un capítulo. El primero era conocer el estado de la cuestión de los estudios sobre ancianos prehispánicos en el área maya y ponerlo en relación con los estudios sobre mujer y género. El segundo objetivo era el de definir qué es lo que los mayas prehispánicos consideraban anciano y averiguar cuál era su aspecto y los rasgos que delataban su edad. En tercer lugar se pretendía conocer cuáles de dichos rasgos sirvieron para identificar a los ancianos en la Iconografía y ver cómo se manifestaron en función del periodo, el soporte y el sexo del personaje. De este modo, se pudo diferenciar a los ancianos de los personajes de edad dudosa y estudiar qué roles desempeñaron y en qué temas participaron, prestando especial atención a las diferencias entre mujeres y hombres; todo lo cual constituye el cuarto objetivo. El quinto fue analizar las representaciones de ancianas a la luz de lo observado y compararlas con lo que dicen de ellas tanto las fuentes coloniales como las actuales, para averiguar cuales tienen un sustento iconográfico y conocer así la posición de las mujeres en sus comunidades. Por último, se creó una base de datos con el mayor número posible de representaciones de ancianos para que sirviese de base a ésta y a futuras investigaciones...

In the first decades of 20th century the just instituted Brazilian Republic faced the challenge to modernize the country. Considering that the progress was associated with the exhaustion of the forest reserves and with climatic changes, two big issues were seen as fundamental: To Fight the Droughts and To Defend the Forests; headed by professionals who were dedicated to these ideals. This research starts from the premise that these were the main challenges enforced by nature to the Brazilian development; the general objective was delimited in the search to understand the meaning and the conception of the natural world by this group of professionals who faced the shock between modernizing the country and conserving its natural resources. Aiming to contribute with the construction of the Brazilian environmental history and to bring historical elements to the debate about the environment in the country, the author concentrates his attention to the analyses, the discussions and the actions that preceded the regulation on the use of natural resources and the implementation of the environmental legislation in Brazil, occurred in 1934. The investigation uses as methodological basis the theoretical directions of environmental history, using sources of data still little explored and valued. In such way, it is taken as starting point some published papers about this subject during the period between 1889 and 1934 in two technical magazines the Revista Brazil Ferro-Carril and the Revista do Club de Engenharia. National engineering played a basic role in this process while arguing, projecting and constructing the development. The formulated proposals, after being divulged, had fomented the interchange with other professionals and had favored the advance of ambient questions in Brazil, in the sense to preserve natural resources, to construct more harmonic relations between the society and the nature and to equate the development with the environment preservation

Droughts surfaced in 1877 as a crucial problem for the birthing Brazilian nation. Engineers, who formed the country's technical and scientific elite, took it upon themselves to study, understand and fight the problem through planned actions of intervention on space. This work, based on proposals and discussions contained in engineering magazines and reports, aims to provide elements for the comprehension of how these systematized actions against droughts, in the Iate nineteenth and early twentieth century, contributed to spatial analysis and the formation of a (then-inexistent) regional and territorial planning discipline in Brazi!. Engineers, by taking up the position of masterminds in the country's modernization, guaranteed for themselves personal economic stability, social prestige and political power. By understanding nature, either as a resource to be exploited or an adversary to national progress, they contributed to the delimitation of the region now known as the Northeast. By seeking to understand the drought phenomenon, they created knowledge about the space they sought to intervene on; by constructing their projects amid political and economical difficulty, they changed the organizational structures of cities and country in the northeast. The proposals for açudes (Iarge water reservoirs) allowed the fixation of population and the resistance against droughts; the roads - railroads and automotive roadways - connected the sertão to the capitais and the coast, speeding up help to the affected populations during droughts and allowing the circulation of goods so as to strengthen the local economies in normal rimes. The adopted practices and techniques, adapted from foreign experience and developed through trial and improvement, were consolidated as an eminently spatial intervention course, even if a theoretical body of regional or territorial planning wasn't formed in Brazil. Regional Planning proper was first applied in the country in the Northeast itself, in the 1950s, based off an economical view of reality in order to achieve development. The engineer's work prior tothat date, however, cannot be dlsconsldered. It was proved that, despite facing financial and political hurdles, engineers had a profound commitment to the problem and intended to act systematically to transform the economical and social relations in the region, in order to be victorious in their struggle against droughts

La restitución de tierras, como instrumento de reparación enel contexto de la justicia transicional, cuenta con importantesherramientas para lograr una acción articulada con los objetivosde justicia social agraria, propios del derecho constitucional ydel derecho internacional de los derechos humanos. Los retosque se derivan de su implementación en escenarios donde elconflicto ha sido originado en buena medida por las desigualdadessociales justifican esta articulación y evidencian su necesidad.La explicitación y la identificación analítica de estos puntos deencuentro son el objeto de este artículo; el referente teóricogira entorno a la potencialidad de la justicia correctiva en lacontribución a la consecución de la justicia social o redistributiva

Determination of Rare Earth Elements (REEs) in the waters and sediments of El Hito Lake and its drainage basin was carried out. Distribution maps for REEs concentrations show increasing values in the lake sediments from the center to the eastern edge reaching 166.5 mg/kg. In the drainage basin, higher values were observed with a maximum of 350.9 mg/kg in the southern part. Concentrations in the water were considerably lower with a maximum value of 1.3 µg/L. Ce, La and Nd were the most abundant elements. When normalized REE concentrations against NASC (North American Shale Composite), a positive anomaly of Eu in the water and of Nd in the sediments (lake and basin) was observed. The (La/Gd)NASC and (La/Yb)NASC ratios determined the predominance of light REE (LREE) over medium (MREE) and heavy REE (HREE). Key-words: Rare Earth Elements, lacustrine sediments and water, Eu anomaly, sulfates RESUMEN: Se llevó a cabo el estudio de Tierras Raras (REEs) del agua y los sedimentos de la Laguna de El Hito así como de su cuenca de recepción. Los mapas de distribución de las concentraciones de REE en los sedimentos de la laguna mostraron valores crecientes desde el centro hacia el margen este alcanzando 166.5 mg/kg. En la cuenca se midieron valores más elevados llegando hasta 350.9 mg/kg en la mitad sur. Los valores en el agua fueron notablemente inferiores, con un máximo de 1.3 µg/L. El elemento más abundante fue el Ce seguido del Nd. Se normalizaron las concentraciones de REEs frente a las del NASC (North American Shale Composite), observándose una anomalía positiva de Eu en el agua, así como de Nd en los sedimentos (laguna y cuenca). Mediante los índices (La/Gd)NASC y (La/Yb)NASC se determinó el predominio de las REEs ligeras (LREEs) frente a las medias (MREE) y pesadas (HREE).
